[0034] Embodiment 1:
[0035] like Figure 1 , Figure 6 and Figure 7 As shown, this embodiment provides a purification and ventilation structure, including a mounting base 11, a guide sleeve 12 and a ventilation pipe 21, wherein the mounting base 11 is arranged on the outer wall of the factory building, the guide sleeve 12 is mounted on the mounting base 11 through a flange member, the ventilation pipe 21 is slidably mounted in the guide sleeve 12, one end of the ventilation pipe 21 penetrates the mounting base 11 and extends into the factory building, and a suspension bracket is preset on the top of the factory building for supporting the ventilation pipe 21 extending into the factory building, thereby improving the placement stability of the ventilation pipe 21;
[0036] The ventilation pipe 21 is connected to the ventilation equipment through a pipeline, and the pipeline can be directly connected to the end of the ventilation pipe 21 away from the factory building (not shown in the figure).
[0037] In order to control the ventilation tube 21 to slide along the axial direction of the sleeve 12, at least one feeding wheel 14 is rotatably mounted on the sleeve 12, so that the feeding wheel 14 and the outer surface of the ventilation tube 21 can be connected through friction transmission. A motor 15 for controlling the feeding wheel 14 to rotate independently is also mounted on the sleeve 12;
[0038] The motor 15 may be a commercially available stepper motor or servo motor.
[0039] When in use, start the motor 15 to drive the feeding wheel 14 to rotate, and drive the ventilation pipe 21 to slide in the guide sleeve 12 through the transmission friction between the feeding wheel 14 and the outer surface of the ventilation pipe 21, so as to adjust the local position in the narrow and long workshop for targeted purification and ventilation treatment. Compared with directly laying a long and large-scale air duct system with more air outlets in the workshop, the above-mentioned scheme of the present application can significantly reduce the cost of the air duct system, and is suitable for use in small-scale dust-free workshops.
[0040] like Figure 1 As shown, a support frame 16 is installed at the lower end of the side of the mounting base 11, so that the column located at the end of the support frame 16 abuts against the bottom middle side of the guide sleeve 12, which plays a role in reinforcing and supporting the guide sleeve 12 and the ventilation pipe 21.
[0041] Embodiment 2:
[0042] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The features of this embodiment that are different from the first embodiment are as follows: Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the pipeline is a side ventilation pipe 13 arranged on the side of the guide sleeve 12, and the side ventilation pipe 13 is connected to a ventilation device. Two side ventilation pipes 13 are provided, and the two side ventilation pipes 13 are symmetrically arranged on both sides of the guide sleeve 12. A valve is provided on the side ventilation pipe 13, and an elastic ring 22 is provided at a position corresponding to the side ventilation pipe 13 on the side of the ventilation pipe 21, and an end seal 31 is provided at the end of the ventilation pipe 21 away from the factory building.
[0043] The two side ventilation pipes 13 are respectively connected to the ventilation equipment for exhausting and supplying air. By switching the opening states of the valves on the two side ventilation pipes 13, targeted air supply and exhaust operations can be carried out to local locations in the narrow and long workshop to achieve the purpose of air change.
[0044] There are multiple elastic rings 22 on the side of the ventilation pipe 21. As the ventilation pipe 21 gradually extends into the factory building, the connection state between the side ventilation pipe 13 and the multiple elastic rings 22 is automatically switched.
[0045] When there is no wind or the wind force is small, the surface of the elastic ring 22 and the side wall of the ventilation tube 21 are in the same virtual cylindrical surface, and a hole of 20-30 mm is left in the middle of the elastic ring 22. The elastic properties of the elastic ring 22 are used to restrict the flow of air, so that most of the air enters and exits from the end of the ventilation tube 21.
[0046] When the ventilation pipe 21 is controlled to move in the guide sleeve 12 to the position where the elastic ring 22 corresponds to the side ventilation pipe 13, the ventilation equipment is started, and the airflow exerts an impact force or a wrapping force on the elastic ring 22, causing the elastic ring 22 to deform elastically, so that the diameter of the circular hole in the middle of the elastic ring 22 increases to 80-90mm, and under the action of the subsequent continuous supply of wind force, the air can smoothly pass through the elastic ring 22, and carry out targeted air supply and exhaust operations to local locations in the narrow and long workshop, thereby achieving the purpose of air exchange.
[0047] Furthermore, in order to reduce the overall length of the ventilation pipe 21, at least one extension pipe 24 can be detachably installed at the end of the ventilation pipe 21 away from the factory building. Multiple extension pipes 24 can be connected in series one by one through a threaded structure or a flange structure and a fastener kit. The side of the extension pipe 24 is also provided with multiple elastic rings 22. According to the need for ventilation at local locations in the narrow and long workshop, the number of installed extension pipes 24 is adjusted to avoid the ventilation pipe 21 and the extension pipe 24 being too long as a whole, resulting in excessive weight of the equipment.
[0048] Furthermore, a filter cartridge 131 is installed on the side ventilation pipe 13, and the filter cartridge 131 is used to filter the air flowing through and intercept the dust in the air, thereby achieving the purpose of air purification and maintaining the air quality in the dust-free workshop; a valve is set between the filter cartridge 131 and the sleeve 12 to prevent the intercepted dust from re-entering the workshop.
[0049] The main body of the end seal 31 is an end cover (not shown in the figure), which is detachably fixedly mounted on the end of the ventilation pipe 21 or the extension pipe 24 to seal the end of the ventilation pipe 21 or the extension pipe 24.
[0050] In addition, the main body of the end seal 31 can also be as follows Figure 6 As shown, an iron core is covered with a rubber sleeve on the outside, and the iron core is located in the ventilation pipe 21. The rubber sleeve covering the outside of the iron core can abut against the inner wall of the ventilation pipe 21 or the extension pipe 24. An electromagnet 32 is installed on the guide sleeve 12. The electromagnet 32 is connected to the iron core through magnetic adsorption coupling, and the end sealing treatment of the ventilation pipe 21 or the extension pipe 24 is automatically switched.
[0051] Embodiment three:
[0052] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The features of this embodiment that are different from the first embodiment are as follows: Figure 3 As shown, in this embodiment, the end of the ventilation pipe 21 is provided with an exhaust pipe I 231 of a bent structure;
[0053] In the present application, the mounting base 11 can be installed at a high or low position according to the location of the main equipment in the factory workshop. When the ventilation pipe 21 is set to extend to the middle area in the vertical direction of the workshop, the exhaust pipe Ⅰ231 with a bent structure is used to perform targeted exhaust treatment on the air in the designated area below the exhaust pipe Ⅰ231.
[0054] Embodiment 4:
[0055] The features of this embodiment that are the same as those of the third embodiment are not described in detail. The features of this embodiment that are different from the third embodiment are as follows: Figure 4 As shown, the extension direction of the ventilation pipe 21 is defined as horizontal. In this embodiment, the end of the ventilation pipe 21 is provided with an exhaust pipe II 232 extending horizontally and longitudinally, and the bottom of the exhaust pipe II 232 is connected with a plurality of branch pipes 233. When the ventilation pipe 21 is arranged to extend to the middle area in the vertical direction of the workshop, the plurality of branch pipes 233 on the exhaust pipe II 232 can more effectively perform targeted exhaust treatment on the air in the designated area below the exhaust pipe II 232.
